Cobalt Version 7 Released

Posted Tue September 01, 2015 @05:54PM

Cobalt Solutions, LLC announces the release of Cobalt V7.0, the latest version of their popular unstructured flow solver. The improvements include a new Overset module along with speed-up in post-processing output and the addition of a few turbulence models.

Cobalt V7.0 introduces a new Overset module which provides improved hole-cuts and improved efficiency. The hole-cut interface is calculated to lie midway between non-cuttable boundaries of overset grids. The result is a very smooth hole-cut -- whether it is a full scale aircraft with tiny gaps in control surfaces or an aircraft with multiple weapons cluster in a weapons release simulation. The implementation of the module follows the same guidelines as found in the flow solver Cobalt Ė robust, accurate, and user-friendly.

The output of flow visualization data has been sped-up. Depending on how many flow variables requested, a speed-up of 2x has been seen in average cases. This can be a valuable time-saver if outputting at a regular interval in a time-accurate job.

Three turbulence models have been added: Hellstenís EARSM (Explicit Algebraic Reynolds Stress Model) and EARSM-CC, and Menterís SST-SAS model. This brings the total number of turbulence models in Cobalt to 16. The complete list and references can be found in the User's Manual.

A 30-day demo Cobalt license and Overset license is available for users to test the new feature for their individual applications. The Overset module requires a separate license in addition to the Cobalt license. Information requests can be sent to contact@cobaltcfd.com.
